Description

The utility model relates to the field of power engineering and can be used to remove free carbon dioxide released in the processes of hydrogen-cation or acidification of water in water treatment plants of thermal power plants and heating networks.

The prototype is a water decarbonization unit containing a decarbonizer, which is a cylindrical body with a nozzle, an irrigation system, a gas outlet pipe from the upper part of the decarbonizer body, and an air supply pipe supplied by a fan to the lower part of the decarbonizer body (USSR Author's Certificate No. 1511212, IPC C02F 1 / 20, 09/30/1989).

The disadvantage of the prototype is the low efficiency of water purification due to the fact that the fan creates an uneven gas velocity profile.

The objective of the utility model is to develop an installation for decarbonization of water, which eliminated the above drawback.

The technical result, which consists in increasing the efficiency of the water treatment process, is achieved by the fact that the installation for decarbonization of water, containing a decarbonizer, in which the nozzle is installed, as well as a source water supply pipe connected to the upper part of the decarbonizer body, an air supply pipe to the source water, a branch pipe for exhausting gases from the upper part of the decarbonizer body, a pipe for supplying air to the lower part of the decarbonizer body, and a branch pipe for decarbonizing water, according to this utility model, additionally contains a flowing nozzle turbulent mixer, built into the feed water supply pipe, and a leveling grid installed under the nozzle in the lower part of the decarbonizer body.

Flowing nozzle turbulent mixer is a nozzle "Inzhem."

The essence of the utility model is illustrated by the drawing, which shows a schematic diagram of the proposed installation for decarbonization of water.

The numbers in the drawing indicate:

1 - pipeline supply of source water;

2 - pipe for supplying air to the source water;

3 - flow nozzle turbulent mixer;

4 - the upper part of the decarbonizer body;

5 - nozzle;

6 - the lower part of the decarbonizer body;

7 - pipe for supplying air to the lower part of the decarbonizer;

8 - leveling grating;

9 - pipe exhaust gases from the upper part of the decarbonizer body;

10 - pipe outlet for decarbonized water.

Installation for water decarbonization contains a decarbonizer, in the case of which a nozzle 5 is installed, as well as a source water supply pipe 1 connected to the upper part 4 of the decarbonizer body, a pipe 2 for supplying air to the source water, a pipe 9 for exhausting gases from the upper part of the decarbonizer body, pipe 7 air supply to the lower part 6 of the decarbonizer body.

The proposed installation for decarbonization of water is characterized in that it further comprises a flowing nozzle turbulent mixer 3, built into the pipe 1 for supplying raw water, and a leveling grid 8, mounted under the nozzle 5 in the lower part 6 of the decarbonizer body.

Flowing nozzle turbulent mixer is a nozzle "Inzhekhim" (Farakhov MI, Kudryashov VN, Laptev AG, Shigapov IM and others. Nozzle for mass transfer columns, certificate of the Russian Federation for utility model No. 17764) .

Thus, the difference of the proposed installation for water decarbonization is that, at a certain concentration of CO ₂ in the source water, it is first fed to the flow nozzle turbulent mixer 3, where the primary water treatment takes place, and only then to the decarbonizer with nozzle 5 and leveling grate 8 where further purification of water from CO ₂ to the required values takes place.

Installation for decarbonization of water works as follows.

The desorption of carbon dioxide is carried out by contact of the source water and atmospheric air. The source water is pumped into the pipe 1. Atmospheric air is supplied through the pipe 2 installed in the pipe 1.

The primary purification of water from CO _{2 is} carried out in a flow nozzle turbulent mixer 3, in which turbulent direct-flow air movement in the form of small bubbles with water through the nozzle "Inzhekhim". Intensive crushing of air bubbles in water occurs in a turbulent mixer 3, the surface of contact phases and the decarbonization efficiency increase.

Secondary purification of water from CO _{2 is} carried out in a decarbonizer, in the case of which a nozzle 5 is installed, under which, to increase the cleaning efficiency, an equalizing grate is installed 8. Primarily purified water with air bubbles is fed to the upper part 4 of the decarbonizer case, where the air is degassed. Next, the water flows down the surface of the nozzle 5 of the decarbonizer and interacts in countercurrent with air.

The air supplied through the pipe 7 to the lower part 6 of the decarbonizer body passes through an equalizing grill 8 installed under the nozzle 5 in the lower part 6 of the decarbonizer body, which makes it possible to evenly distribute the air flow. Gases are discharged through the pipe 9, and decarbonized water is discharged through the pipe 10.

Thus, a two-stage water decarbonization unit has been developed, in which, to increase the efficiency of the decarbonizer, a leveling grid 8 is built into the lower part of the decarbonizer casing, which makes it possible to evenly distribute air over the entire area of the decarbonizer. For a more effective treatment of carbon dioxide, the initial water is subjected to primary treatment in a nozzle turbulent mixer 3.

Using the proposed utility model will improve the efficiency of the installation for decarbonization of water due to two-stage water treatment. The water treatment efficiency in the flow nozzle turbulent mixer 3 is η ₁ ≈80-90%, and the water treatment efficiency in the decarbonizer with nozzle 5 and leveling grating 8 is η ₁ ≈95-98%, while the total water treatment efficiency will be
